To all whom it may concern:

Beit known that we, FRANCESCO DEMARIA and CARLO RANZINI, subjects of the King of Italy, residing at the city of New York, borough of Manhattan, in the'county and State of New York, have invented a new and I'mproved Acetylene-Gas Gene'rator,- of which the following is a full, clear, and exact description. I v

The object of the invention is to provide a simple, durable, and economical machine for generating acetylene gas wherein the genera tor and holder directly cooperate.

Another object of the invention is to so construct the machine that itwill produce a very dry gas and will automatically regulate .the generation of gas in accordance with the amount consumed and at all times maintain a uniform pressure.

A further object of the invention is to provide an automatic supply for andlcheck of the Water fed to the calcium'carbid, the'water be-' ing delivered thereto in a spray.- i i It is also an object of, the invention to pro-' vide means for automatically controlling the supply of water to the generator during the process of cleaning the same.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both figures.

Figure 1 is a side elevation of the improved generator, and Fig. 2 is a vertical section taken centrally through the same.

The generator A is in'the form of a tank, and the bottom 10 inclines downward from the sides toward a central bottom outlet-pipe 11. The generator A is surrounded by a jacket A, preferably of less thickness than the generator, and the space 12 between the jacket and generatoris adapted to be filled with water. A column ofooil may be placed upon the surface of the water to prevent rapid evaporation. The jacket A closely surrounds the outlet-pipe 11, and this pipe 11 is provided at its lower end with a valve 13. The pipe 11 and valve 13 are utilized to discharge the .lime that accumulates in the bottom of the generator, and a cook 14 is located at the botwhenever the water in the drawn off. l I The holder B consistsof a top 15, provided withan opening normally closed tightly by a plug 16 and a cylindrical body 17. The lower end of the body portion of the holder enters the space between .the generator A and its jacket A. as shown in Fig. 2. The vertical movement of the holder is directed through the medium of rods 18, attached to the top of the holder and'extending downward outside of the jacket A through guides 19, as shown in both figures.

' A tank 0 is secured to the under face of the top of'the holder, and a receptacle D for calcium carbid extends through the top of the tank, as shown in Fig. 2, being attached in a water and gas tight Iman'ner to both 'of said parts. The gasesca'pes from the generator through a stand-pipe 22, and this pipe is car-' ried out througha side wallof the generator and the side wall of the jacket and at its outer end is provided with 'a'purifier 23 and a stop-cock 24:. The structure 'is supported preferablyby legs 20, but the legs ..are not usually attached directly to the tankybut to a ring-base 21, that extends around the bottom portion of the tank near its outer side, as shownbest in Fig. 1.

A vertical .yoke 23 is secured to the upper portion of the receiver D, and a threaded stem 24: is passedthrough said yoke, the cover 25 for the receiver beingcarried by the bottom portion of saidstem', so that when calcium carbid is tobe placed in the receiver D the cover may be raised, and as soon as the .receiver has been charged the. cover. may be ceiver.

The bottom 26 of the receiver is hinged at its side and is held closed byan attached weight 27; but the weight of the .carbid introduced into the receiver will overcome the weight attached to the bottom 26, and therefore the bottom will open and the charge in holder and through the bottom portion of said tomportion of the jacket A, which isopened space 12 is to be.

tightly closed against the upper end of the rethe receiver will drop to the bottom of the generator A.

VVateris introduced into the tank 0 through a supply-pipe 28, provided with a suitable valve 29, and that portion of the pipe that extends within the tank 0 is provided with an upturned terminal 30, and the outlet end of the pipe is adapted to be closed by a valve 31, fulcrumed upon a suitable support 32, and this valve is controlled by a float \Vhen the water in the tank 0 reaches a given level, the float 33 is raised to such an extent that the valve 31 will seat itself. When the water is below the said level, the valve automatically opens and permits a further supply of water to the tank.

A strainer 34 is located in the bottom of the tank 0. This strainer is connected with a valve 35, preferably located within the tank C, as illustrated in Fig. 2, and the plug of the valve is regulated through the medium of a rod 36, that extends upward and outward through the top of the holder. This valve 35 is closed only when the machine is not in operation. A pipe 37 is connected with the valve 35. This pipe extends downward within the generator A to about the central portion thereof and terminates in a rose or sprinkler 3S, and above this rose or sprinkler a valve 39 is located, theplug whereof is attached to a stem 40, provided with a crank-arm 41, and a rod 42, provided with a float 43, is pivotally attached to said crank-arm, said rod being fulcrnmed upon a bracket 44, that extends, preferably, from the central portion of the rose or sprinkler, as shown in Fig. 2. This valve is normally open and is closed only when water has accumulated in the generator sufiicient to raise the float 43 while said generator is being cleaned. A cut-off valve 45 is located between the upper valve 35 and the lower valve 39. The plug of this cut-off valve 45 is attached to a weighted arm 46, and said arm 46 is pivotally connected with the lower end of a bracket 47, which bracket is practically an inverted-U-shaped rod, one member whereof is attached to bearings 48, carried by the inner face of the body of the holder, the other member being attached to a bearing 49, secured upon an end of the tank 0. Thus the bow portion of the bracket 47 extends across the upper edge of the generator.

In the operation of the machine the calcium carbid is fed into the generator in the manner described, water is turned on at the supplypipe 28, and the valve 35 is opened, and the cut-oil valve 45 will be fully opened by reason of the holder being in its lowermost position. The water from the tank 0 will then pass through the pipe 37 to the rose or sprinkler 38 and will be sprayed upon the calcium carbid, thus generating gas,which passes through the supply-pipe 22, the stop-cock 24 having been opened. "When the pressure of gas in the machine is such that the holder or bell is raised sufliciently to carry the bracket 47 out of engagement with the top of the generator A, the weighted arm 46 will automatically close the cut-olt valve 45; but as the pressure in the machine is reduced and the holder or hell lowers as soon as the bracket 47 engages with the top of the generator A the cut-01f valve will commence to open and water is again supplied to the carbid, renewing the process of generating the gas.

hen the generator is to be cleaned, the lime is dumped out by opening the valve 13 at the bottom of the machine. turned on at the supply-pipe 28, the valve 35 being open, and when the generator has received a suificient quantity of water the float 43 will be raised and the valve 39 will be closed, thus stopping the supply of water to the generator. The water is permitted to remain for a given length of time in the generator and is then drawn 0E and the generator again charged with water, and when the water reaches a predetermined level it will again be shut off. This operation is repeated until the generator is thoroughly cleaned, whereupon the valve 35 is closed.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- 1. A generator for gas, a jacket inclosing the generator and adapted to contain liquid,
